What scale factor was used in going from the grey triangle to the yellow triangle?

Mathematics
1 answer:
s344n2d4d5 [400]4 years ago
7 0

Answer:

The scale factor used was 2

Step-by-step explanation:

see the attached figure with letters to better understand the problem

we know that

A dilation is a non-rigid transformation that produce similar figures

If two figures are similar then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

In this problem the dilation going from the grey triangle to the yellow triangle is an enlargement and its equal to the quotient length side AC by length side DE (corresponding sides)

we have

AC=\left|4-(-8)\right|=12\ units --->absolute value of the difference of the x-coordinates

DE=\left|2-(-4)\right|=6\ units --->absolute value of the difference of the x-coordinates

\frac{AC}{DE}=\frac{12}{6}=2

therefore

The scale factor used was 2

Draw the graph of the equation<br><br> x+y=5
Advocard [28]

well first you have to get x and y on separate sides so subtract x by both sides to put x on the right side.

now you have y = 5 - x

to graph that let's throw in some numbers for x and y and make a function table

x, y

1, 4

2, 3

3, 2

4, 1

5, 0

6, -1

and so forth

as you can see as x increases in value, y decreases in value

all you have to do now is plot those points on a graph

Artist 52 [7]
The first question is this: the smallest square is square A, and that is 9 units. and square E is two times that, and so on.

Square A's side length is 9 units and the area is 81.
Square E's side length is 18 and the area is 324.
Square C's side length is 27 and the area is 729.
Square B's side length is 36 and the area is 1,296.
Square D's side length is 45 and the area is 2,025

Which decimal is closest to 1/6
lorasvet [3.4K]

This definitely sounds like a question where there are
some choices listed but you decided not to share them.

Let's say you have several decimals that all look like this:

0.166
0.166666
0.1666
0.16666666666
0.16
.
.

The one with the most 6s is the closest to 1/6 .

Can you ever write a decimal that's exactly equal to 1/6 ?

No, you can't.  The 6s go on forever, and never end. 
The more 6s there are, the closer it is to 1/6, but it
can never be exactly 1/6 .
